Feature

The Dawn Machinery DN-Series Vertical Grinding Machine is a high-precision vertical cylindrical grinder engineered for grinding internal diameters (ID), external diameters (OD), and end faces of heavy, large, and non-circular workpieces. Its rigid double-column structure and vertical machine layout provide exceptional stability, superior machining accuracy, and outstanding load-bearing capability for demanding industries such as aerospace, heavy equipment, energy, bearing, gear, and precision component manufacturing. Designed for maximum production flexibility, the machine supports single- or double-spindle configurations, automatic tool changing, power dressing, and customized workholding solutions. Combined with advanced FANUC or Siemens CNC controls and conversational programming, the DN-Series delivers high productivity, consistent precision, and simplified operation while reducing setup time and improving overall manufacturing efficiency.

Product Introduction

Double-Column Machine Structure

A heavy-duty double-column frame provides excellent structural rigidity, minimizes vibration during grinding, and maintains machining accuracy even when processing large and heavy workpieces.

Vertical Rotary Worktable

The precision rotary table securely supports the workpiece while utilizing gravity for stable clamping. This design is ideal for large-diameter, heavy, and irregular-shaped components.

High-Speed Grinding Spindle

Available in single or dual-spindle configurations with various spindle speeds, allowing both rough and finish grinding using different wheel sizes and RPM ranges.

Automatic Tool Changer (Optional)

An automatic tool changing system enables fast wheel replacement, reducing non-cutting time and increasing machining flexibility for multi-process grinding.

Power Dressing Unit

Automatically dresses the grinding wheel to maintain wheel geometry, improve surface finish, and ensure long-term grinding accuracy.

Tool Diameter Measurement System

Automatically measures grinding wheel diameter after dressing, ensuring precise compensation and maintaining dimensional accuracy throughout production.

Wireless Online Measurement

Optional in-process measurement continuously monitors workpiece dimensions, reducing manual inspection and improving process consistency.

Workholding Systems

Multiple fixture options are available to accommodate various applications, including:

  • Electromagnetic Chuck 
  • Hydraulic Chuck 
  • Mechanical Chuck 
  • Customized Fixtures 
  • Zero-Point (Origin) Fixture
